Abstract
A method and a device for obtaining a sum of products which are applied to a spatial filter in a picture processing system, a transversal equalizer in radio communication equipment or the like, are based on the division of a portion of or entire operand by a predetermined figure length. The sum of products is first calculated among the operands having the same figure position, and the obtained results are added while shifting the figure in response to the divided figure length and the figure position. The lower figures, which do not need to be added, are then appended under the lowest figure of the addition result as is. Thus, the scale of the figure processed in an integrated circuit (IC) is decreased and the application of an IC of identical rating is further promoted.
